Vulnerability is a level 66 Magic spell. When cast on an opponent, their defence level is reduced by 10%. The spell gives 76 Magic experience per cast and requires 1 Soul, 5 Earth, and 5 Water runes to be cast. The spell can only be cast if his stats haven't already been lowered, meaning you cannot stack stat reduction with multiple spells in a row.

Remember, you cannot use Ancient Magicks or Lunar spells if you are using standard spells.
